ンモータ。A cup-shaped case made of sheet metal, a rotor body made of a permanent magnet fixed to the inner peripheral surface of the case, and a rotor shaft fixedly attached to the center of the bottom of the case so as to protrude inside the cup. Ultrasonic vibration is applied to the inner diameter surface of the end bracket of the synthetic resin propeller mounting hub, which has a rotor consisting of In a fan motor having a structure in which a propeller and a rotor are welded together to form an integral rotating body, a plurality of depressions are formed in the outer periphery of the cup-shaped care plate near the bottom surface to which the end bracket is welded. These recesses are provided so as to protrude inward with a depth deeper than the thickness and an axial length slightly longer than the axial length of the inner diameter portion of the end bracket, and along the circumferential direction at a midpoint of the axial length of these recesses. A fan motor characterized in that a groove having a depth shallower than the thickness of a case sheet metal is dug to prevent a propeller mounting hub from being removed from a cup-shaped case.
